About

This dashboard shows results from the Berkeley Interpersonal Contact Survey (BICS) in Spring 2020.

Caveats / underway:

  • These results show the national and city samples pooled together

  • the values presented here do not yet have principled uncertainty estimates. That is coming soon!

This project has been approved by the UC Berkeley IRB (Protocol 2020-03-13128).

Contact definition

Respondents to the survey were told to consider someone a contact using this text:

We would like to ask you some questions about people you had in-person conversational contact with yesterday.

By in-person conversational contact, we mean a two-way conversation with three or more words in the physical presence of another person.

You might have conversational contact with family members, friends, co-workers, store clerks, bus drivers, and so forth.

(Please do not count people you contacted exclusively by telephone, text, or online. Only consider people you interacted with face-to-face.)
